Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2 This utility model provides a technical solution: a hazardous waste incinerator, including an incineration chamber 1, a purification tower 2, and a feeding rack 3. The discharge end of the feeding rack 3 is connected to the upper part of one side of the incineration chamber 1, and a feeding hopper 4 is provided on the feeding end of the other side.

The lower part of the feed hopper 4 is rotatably mounted with a crushing shaft 10. The side wall of the crushing shaft 10 is provided with a plurality of moving crushing blades 11 along the axial direction. The inner wall of the feed hopper 4 is provided with fixed crushing blades 12 that are staggered with the moving crushing blades 11. The rotating shaft 7 is connected to the crushing shaft 10 through a drive assembly. The upper part of the incineration chamber 1 is provided with a flue pipe 13. The lower part of the side wall of the purification tower 2 is provided with a dust collection box 14. The dust collection box 14 is connected to the purification tower 2 through a ventilation port. One end of the flue pipe 13 is connected to the side wall of the dust collection box 14. The dust collection box 14 is provided with a dust collection assembly. The purification tower 2 is provided with a spray assembly.

[0020] By adopting the above technical solution, hazardous waste is fed into the feed hopper 4, initially crushed by the crushing roller 8, and falls onto the crushing shaft 10. The moving crushing blade 11 and the fixed crushing blade 12 work together to further crush it. The crushed waste is then sent to the incineration chamber 1 for incineration by the conveying auger 5. The flue gas generated by incineration enters the dust collection box 14 through the exhaust pipe 13. After the dust collection component removes the dust, the flue gas enters the purification tower 2 through the ventilation port. The spray component purifies the flue gas and then discharges it from the exhaust pipe 26. This solves the problems of insufficient treatment and serious pollution caused by traditional equipment, and improves the efficiency and environmental protection of hazardous waste treatment.

[0021] In this embodiment, the driving assembly includes a second motor 15 disposed on the outer wall of the feed hopper 4, one end of the rotating shaft 7 opposite to the gear 9 passes through the feed hopper 4 and is fixedly mounted with a first pulley, the driving end of the second motor 15 is connected to the end of the rotating shaft 7 near the first pulley, one end of the crushing shaft 10 passes through the side wall of the feed hopper 4 and is mounted with a second pulley, and a transmission belt 16 is wound between the first pulley and the second pulley.

[0022] By adopting the above technical solution, the second motor 15 starts and drives one side shaft 7 to rotate. Through the meshing gears 9, the other shaft 7 rotates in the opposite direction, realizing the opposite rotation of the crushing roller 8 to crush the waste. At the same time, the first pulley rotates with the shaft 7, and drives the second pulley and the crushing shaft 10 to rotate through the transmission belt 16, so that the moving crushing blade 11 can perform crushing operations.

[0023] In this embodiment, the dust removal assembly includes a filter screen 17 disposed in the dust removal box 14, a main shaft 18 rotatably installed in the purification tower 2, one end of the main shaft 18 being connected to a third motor 19, and the other end extending into the dust removal box 14 through the filter screen 17 and fixedly installed with a pair of cleaning brushes 20, the third motor 19 being fixedly installed on the outer wall of the purification tower 2, a dust collection port 21 being provided on the lower wall of the dust removal box 14, and a dust collection box 22 being detachably connected to the dust removal box 14 below the dust collection port 21.

[0024] By adopting the above technical solution, the flue gas generated by incineration enters the dust collection box 14, the filter screen 17 filters the dust in it, the third motor 19 drives the main shaft 18 to rotate, which drives the cleaning brush 20 to rotate and clean the surface of the filter screen 17 to prevent dust from clogging the filter screen 17. The cleaned dust falls into the dust collection box 22 through the dust drop port 21. The dust collection box 22 can be removed and cleaned periodically.

[0025] In this embodiment, the spray assembly includes a spray pipe 23 located in the upper part of the purification tower 2, a plurality of nozzles 24 are provided on the lower wall of the spray pipe 23, a packing layer 25 is provided inside the purification tower 2 and above the ventilation opening, and an exhaust pipe 26 is provided at the top of the purification tower 2.

[0026] By adopting the above technical solution, the flue gas after dust removal enters the purification tower 2, passes upward through the packing layer 25, and the spray pipe 23 can be connected to external liquid delivery equipment, such as water pump delivery pipe, etc. The nozzle 24 sprays out liquid, and the liquid forms a liquid film on the surface of the packing layer 25, which fully contacts the flue gas and absorbs the harmful gases in the flue gas. The purified gas is discharged from the exhaust pipe 26.

[0027] In this embodiment, the dust collection box 14 is further configured to have a shaft bracket for supporting the main shaft 18.

[0028] By adopting the above technical solution, when the main shaft 18 rotates under the drive of the third motor 19, the shaft frame supports the main shaft 18 and prevents the main shaft 18 from shaking due to its long length.

[0029] In this embodiment, the incineration chamber 1 is further configured such that a sliding door is provided on the front wall.

[0030] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0031] Example: Hazardous waste is fed into the feed hopper 4. The crushing roller 8 initially crushes the waste, which then falls onto the crushing shaft 10. The moving crushing blade 11 and the fixed crushing blade 12 alternately shear the waste, further crushing it into fine particles. The crushed waste is then conveyed to the incineration chamber 1 by the conveying auger 5. The hazardous waste in the incineration chamber 1 is burned at high temperature. The flue gas generated during combustion enters the dust collection box 14 through the exhaust pipe 13. After entering the dust collection box 14, the filter screen 17 intercepts the dust. The main shaft 18 drives the cleaning brush 20 to rotate, cleaning the dust on the surface of the filter screen 17 to prevent clogging. The cleaned dust enters the dust collection box 22 through the dust inlet 21. The flue gas that has passed through the dust collector enters the purification tower 2 through the ventilation opening and flows upward through the packing layer 25. The nozzles 24 of the spray pipe 23 spray liquid, which forms a liquid film on the surface of the packing layer 25, making full contact with the flue gas and absorbing the harmful gases in the flue gas. The purified gas is discharged from the exhaust pipe 26.

[0032] After processing, open the sliding door to clean the ash inside the incineration chamber 1, remove the dust collection box 22, and centrally process the collected dust for the next operation.
